I'm very happy with the service I've been given today!  They came out the same day I called them on a really hot day and were able to diagnose the problem quickly, and for free.  Unfortunately the unit I have is 18 years old and they had to really search for replacement motor as it was no longer made.  It only took 2 days to complete the job and the technician worked during the hottest part of the day around 97 degrees.  

I would use them again should I have the need.  Service is warranted for one year.
